Tod-ZZ who@ it. irl/ ally concern/.1' Y Beit known that LC nARLEsW. SCHWARTZ, Jr., a'citizen-of the United States;"res id'n'g in .Phladelplluin Pennsylvania, have .invented certain "provementsin'Driers, oi' which the following is a specification. My invention relates' .to

catedl vat the ytop of thedrying-chamber for` fo circulating the air through the saidchamber. and* through heating-chambers at the sides ofV the drying-chamber'.

The `present ihhchine illustrates 'a con- 'struction in which the fan directs theci'irrt-int r 5 of air'downwardly'in saidv chamber, -the volthrough the'heating- -ume of air then risi chambers, entering -t e top of the dryingchamber, and being again forced vdmzvnvvardly therein. It will be understood that the zo rcction of the air may be reversed, desired.. The object of my invention is to" revent.

the heating and dryingoutof the lu ricantv in the bearings for' the vertical shaft whichY carries the horizontal fan.

The invention also relates to the particular construction ofthe supports for the said vertical shaft.

.In the accompanying drawings, F shows a transverse vertical section of suli- 3o cientof a drying-machine of the character to which my invention relates to illustrate said invention, and Fig. 2 isan enlarged section of part of the device.'

-In Fig. 1 of the draWin'gsf-l represents the 3 5 outer casing of the machine, and 2 a vertical Shaftifree tc turn in bearings Sand 4, `carried, respectiveiy, by cross-beams 5 and 6 ofthe structure, said shaft being' provided at its oWer end with a rotary fan 7, havinga solid 4o central portion 8 of considerable area, usually `about one-third ofthe diameter of the fan.

The structure contains a drying-chamber 9 and heating-chambers 10 at eachside of the same, provided With steam-coils or other available air-heating devices, relatively' short internal partitions 1 1 causing thel air to fol- .low the courses indicated by the arrows when the fan 7 isproperly rotated.`

Surrounding'a-central opening 1n the top 5o ofthe casing 1 and depending from the latter is a cylindrical shield. or guard 12, which is of adiameter substan tially coincident with that of the ixnperforate center 8 of the rotary fan,

that classof dry-. 2 and it"sjhearings'.A lI-lfence the heatin ofthe ing-machines in which a horizontal fan is'lofor the 'shaft 2, ,sai

' of the shaft is adapted a split collar 14, which igure 1` the lower edge ofsaid cylindrical shield or guard. 12 approaching closely to the upper 5 5 surface of-t eclosed center 8 ofthefan. By* reasonof this construction the currents of hot air circulating in the upperportion of the drying-chamber 9 cannot gain access to the shaft 6o latter and the drying pout ofthe lu ricant therefor are eiiectu'ally prevented, especially "when the space within the cylindrical shield or guard 12 isopen to the air-at the top', as showninFig.

`ln order to provide dproper vvertical support "shaft isgrooved, as

shown at 13 2 'in Fig. 2, at a point above the 4lower;bearing 4, andto this grofived'portion rests upon the top of the bearing 4, and thus provides vertical su portfor the shaft.

In like manner t ehub ofthe fan is su ported upon.' the shaft 2 by means'of a split collar 1.5, 'adapted to "a -grooved portion 16 75 of saidshaft below the hublot the fan.
